Thai name: Som
Season: all year
This is among the sweetest and the juiciest of oranges, with a yellowish-green peel and bright yellow flesh; the segments are generally eaten fresh or squeezed for their juice. The main season is September through November, but some sweet oranges can be found in the markets all year round. Tangerines (som khiao wan in Thai) are also grown extensively in Thailand and eaten in the same way as the oranges.
